php - 此付款请求必须由发件人授权 - Paypal

Question

好的，这是我所做的:

1. 创建了一个 PayRequest

2. SetPaymentOptions - https://developer.paypal.com/webapps/developer/docs/classic/api/adaptive-payments/SetPaymentOptions_API_Operation/

3. ExecutePayment - “此付款请求必须由发件人授权”。我不知道为什么我无法执行付款。据我了解，一旦我成功执行付款，我将获得一个 payKey，我将使用它来将用户重定向到 paypal。 https://developer.paypal.com/webapps/developer/docs/classic/api/adaptive-payments/ExecutePayment_API_Operation/

附件是我使用的源代码。这些值都是硬编码的。我已经尽力浏览了类似的问题，这对我来说毫无意义，因为它与我的理解相矛盾。一些答案指出，在您执行付款之前，买家需要先批准付款。

我只想在到达paypal登录页面时查看所有项目的详细信息。

Answer 1

希望我理解正确。

对我来说，您似乎跳过了用户需要授权付款的步骤。当您执行支付(创建)操作时，您应该会在 PayPal 的响应中看到一个 RedirectURL。您需要将用户重定向到此 URL，以便他们授权在 PayPal 上付款。

一旦他们批准了付款，您就可以执行付款了。

您的步骤需要更改为:

1. 创建支付请求
2. 设置付款方式
3. 重定向到 PayPal(来自 PayRequest 响应的 RedirectURL)以进行用户授权
4. 如果授权，执行付款

PayPal 在 the Pay API operation page 上对此进行了提示

在发件人登录 PayPal 并批准付款后将发件人的浏览器重定向到的 URL；它始终是必需的，但仅在付款需要明确批准时使用

在第 3 步之后，用户将返回到您在 $data['returnUrl'] = $returnURL;

中提供的 URL
